HAND VISE.

APPLICATION FILED JAN.19, 1909.

Patented Apr. 27, 1909.

To all fwhom it may concern:

Beit known that I, JOHN G. SMITH, a citi'- zen of the United States, residing at Wahoo, in the county of Saunders and State of Nebraska, have invented a new and useful Hand-Vise, of which the following is a specification. l f l The present invention is a gripping tool in the nature ofahand vise, embodying certain novel features lof construction,` to be hereinafter described and claimed.

The object ofthe invention is'to provide a .novel jaw adjustment, and also `to provide a jaw structure, and means for o erating 'the jaws, which enables the toolto e used as a wrench and pliers. l .l

TheA invention is illustrated in the accomv. PIlyiIlg drawings, in which Flgure'l is lan elevation of thetool, parts `being shown broken away; Fig. 2 is a trans verse section'on the'line2-2 of Fig. 1.

Referring more particularly to .the drawing, 5 denotes a pairof Shanks, which are spaced apart and loosely connected at one kend by a cross-bar 6. At the other end, the

Shanks are formed into gripping jaws 7, having planefaces 8,- and concave faces 9, the latter faces being adapted to be used when the t'ool is employed lto lgrip a pipe or other rfound object. The jaw "faces are serrated,

. as usual. lAls already stated, the connection between the Shanks 1s a loose one, the crossbar 6. being formed'with openings `-10, .in

which` reduced ends l1.1 ofthe LShanks fit.

Said-V reduced ends terminate in hooks 12, which project over the outer edge of the openings ,10, and serve to prevent the Shanks 5 from 'pulling' out of sald. opel'iings.4 The reduced l ends 11 of the Shanks are also rounded or curved, as indicated at 1'3,1so that said ends may rock in the openings 10 when the'shanks are swung toward or 4from each hat one end ahead or enlargement 16, tol which the links'14 are pivoted, as indicated.

other, to -close or open the jaws'.

To'the jaws 7 are pivoted links 14, which are also pivotallyconnected to athrust rod 15, to form a'toggle. `The thrust rod'15 .has

at 17, by means of a 'transverse bolt or other suitable connection. The links 14 lare pivotedto `the jaws by transverse vbolts 18 or other suitable connections. 4A pair of links 14. is connected to each of the jaws 7, as

herein described, on both sides thereof, be tween which the head 16 is received. Each of the jaws 7 is recessed on one side, as indi- Speci-cation'ef Letters Patent. application mea January 19, 190e. serial No. 418,124.

cated at 19, in which recess one of the links 14 works. These recesses serve as stops to limit the opening movement of the jaws, and also permit connection with thefhead 16 .to

be made without the use of washers, the

depth ofthe recesses 19 being the same as'the thickness of the links, so that one link may extend Hush with the side of the head to which it is connected, and theother link eX- tend flush with the' outer surface of said link.

Between the head 16 andthe cross-bar 6, a sprm Said rol is also screw-threaded at its end opposite the head,l 'as indicated at 21, and `on said threaded end is mounted a wing nut 22.

The threaded endfbf the rod terminates in a' ybeveledportion` 23, which maybe used as a screw-driver. The threaded portion of the rod extends loosely through an opening 24 -in the cross-bar 6, said opening being countersunk at its outer end, so'that the threads cannot pull against the cross bar. v The l20 is coiled around the rod 15.

wing nut 22 is screwed on. the threaded portion 2.1 of the rod to engage behind the crossbar, and .is for the ur 'ose of adjusting the jaws, as well'as for ociing them on the.ob-' ject to be held. The base of the wing nut seats inthe countersink of the opening 24. A ou theA The jaws are closed ,by a gr1 Shanks 5, and they are opened by t e' spring 20. When it is desired to lock the jaws on the object, the stem 15 is drawn downfy wardly by the win nut` 22 until the jaws firmly grip the wor and, as Ithe wing nut is in enga ement with'the cross-bar 6,' lthe the wing nut in the opposite v directionfthe spring 20 pushes the rod 15 -up\vardly,arid, through the toggle, spreads the jaws, vand the work is thus released. f

The tool herein described is simple in Iconstruction, and effectually serves-the l.pur ose for which it is designed. By reason ofp the shapeof the'jaws, as well as the means fo'r operating the same, the tool maybe usedvas awrench, pliers,tweezers, .and a hand vise,

and, by the' shape of the jaw faces, flat and round objects may be held with equal facilit yWhat is claimed is 1 l'. A hand. vise comprising a pair of shanks formed at one end with jaws, a cross-bar loosely connecting the `other ends of the Shanks andformed with an opening intermediate thereof, toggle-links connected to the jaws, a'thrust rod operatively` connected 'work will e securely held.4 Upon turning to the toggle-links and extendingthrough the opening in the cross-bar, said rod being screw-threaded, and a nut screwed on the rod and engageable behind the cross-bar.

2. A hand vise comprising a pair of shanks formed at one end with jaws, and having at the other end reduced, hook-sha ed ends, a cross-bar connecting said reduce ends, said cross -bar having openings in which said ends loosely seat,v toggle-links connected to the'jaws, a thrust rod operatively connected to the toggle-links, and means for oper-- ating the'thrust rod. l i

3. A. hand vise comprising a pair of Shanks formed at one end with jaws, a cross-barA loosely connecting the other ends of the Shanks, toggle-links connected to the Ijaws', a thrust -rod having an enlargement to which the toggle-links are connected, a

spring coiled around the thrust rod be` tween said enlar ement and the cross-bar, and means for loc 'ng the thrust rod against movement in a direction to open the jaws.

4. A hand vise comprising a pair of Shanks formed at one end with jaws, a cross-bar loosely connecting the other ends of the Shanks and formed with an opening intermediate the same, toggle-links connected tot the. jaws, a thrustJod operatively connected tothe toggle-links and passing-through the opening in the cross-bar, said thrust, rod being threaded adjacent to said opening and havin an abutment, anut screwed on said threa ed portion and engageable behind the cross-bar, and a spring engageable at its ends with the opposite side of the cross-bar and the abutment of the thrustl rod, respectively.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
